Phono amp picking up radio station from turntable rca’s

So just got a Mark Levinson preamp with built in phono preamp. Running 2m rca interconnects from turntable as it sits away from other gear and now picking up a local AM radio station. What are solutions to remove this other than moving turntable and 1 meter rca’s. Would a step up transformer work ? Before my setup was phono preamp next to turntable with short interconnects and running Balanced XLR 2 meter cables to preamp and did not have this issue. Any help and suggestions would be appreciated.
